Embodiment
Below in conjunction with accompanying drawing, scheme of the present disclosure is described in detail.
Fig. 1 is the block diagram of the structure schematically shown according to signal testing interconnecting device 100 of the present disclosure.Signal testing interconnecting device 100 comprises: input interface 101, and it comprises n road parallel input channels; Comprise the disconnection block array 102 of n disconnection block; Output interface 103, it comprises n road parallel output passage.Here, the n road parallel input channels of input interface 101 is connected to the n road parallel output passage of output interface 103 respectively via n disconnection block.Here, n be more than or equal to 2 integer.Please note: disconnection block can select the disconnection block of available any model on market.Input interface 101 can such as but not limited to being implemented as ZIF connector plug and cable.And output interface 103 can such as but not limited to being implemented as ZIF connector body.
Utilize n isolating switch each on signal take out and draw a little, optionally can carry out signal testing.But due to the restriction of signal voltage, be difficult to utilize signal processor automatically to test the signal on isolating switch.Fig. 2 illustrates the circuit diagram with a signalling channel 200 in the signal testing interconnecting device of Signal-regulated kinase according to disclosure embodiment.As shown in Figure 2, Reference numeral 201 and 203 distinguishes 1 tunnel signalling channel in the n road signalling channel of the input interface 101 shown in index map 1 and output interface 103.One of n disconnection block in disconnection block array 102 shown in Reference numeral 202 index map 1.The signal of Reference numeral 202a instruction disconnection block 202 is taken out and is drawn a little.Utilize this signal to take out and draw the manual detection that a 202a can carry out signal.
A signalling channel 200 in signal testing interconnecting device can comprise, and in other words, arranges Signal-regulated kinase 204 for each disconnection block.Signal-regulated kinase 204 is disposed in the output terminal of each disconnection block 202, for nursing one's health signal.
In the embodiment of fig. 2, Signal-regulated kinase 204 is implemented as voltage divider.Wherein, the dividing potential drop of resistor R1 and R2 (or R3) is supplied to output interface.R2 and R3 represents that the resistance of this divider resistance is variable.In other words, the resistance of this divider resistance can switch between R2 and R3.Be not limited thereto, the resistance of this divider resistance also can change between more resistance value.The tissue of R1, R2 and R3 is preferably mega-ohms.Reference numeral 205 represents a signalling channel in the parallel output passage of n road.
In addition, in embodiment further, Signal-regulated kinase 204 can also comprise resettable fuse Rr.It is arranged on the upstream position of output interface, to protect the processor for automatically testing better.
By the introducing of output interface of signal after Signal-regulated kinase and conditioning, solve in system testing process the protection problem taking out fuse number, meanwhile, the concurrent testing interface of band defencive function can be provided while manual test interface is provided.Two kinds of signal measurement modes can be carried out simultaneously, can reduce the probability gone wrong in test process.
Fig. 3 is the figure of the card extender schematically shown as the specific implementation according to signal testing interconnecting device of the present disclosure.
As shown in Figure 3, Z1 plug and Z2 socket, by test adaptor case access pilot system, ensure that former test signal connects.Manual test signal take out draw point (disconnection block) can to single line take out pilot measurement examination, the testing apparatuss such as external multimeter, oscillograph.Z3 test plug band defencive function test plug, mainly connects Auto-Test System, adjusts by adjustable gain Switch Controller signal amplification factor meanwhile.
Below in conjunction with Fig. 3, the embodiment under a concrete scene is described.
Among aircraft utilities experimental enviroment, excitation set (for airborne equipment provides pumping signal) or collecting device (gathering airborne apparatus output signal) adopt cable to be connected with airborne equipment.On stube cable, the general 156 pin ZIF connectors that adopt are as Signal separator face, when signal demand is tested, disconnect parting plane ZIF connector plug and are connected with socket, access 156 road signal testing transfer boxes, take out pilot measurement examination to signal.
After 156 road signal testing transfer box access experimental enviroments, by Z1 plug, Z2 socket, ensure the integrality of former circuit.
Method of testing one (manual test): taken out by the manual test signal on disconnection block and draw a little, tester measures signal by multimeter or oscillograph, observing system working signal state.
Method of testing two (automatically testing): taken out by Z3 test signal and draw plug, can be connected with external test macro, automatically complete the follow-on test of related system working signal, also adjust by adjustable gain Switch Controller signal amplification factor meanwhile.
The above; be only specific embodiment of the present disclosure, but protection domain of the present disclosure is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the disclosure discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present disclosure.Therefore, protection domain of the present disclosure should described be as the criterion with the protection domain of claim.
